With your created yoroi wallet you are now able to receive ADA to delegate.
In this example Binance is used. It should work similarly with any other trading platform.
Open your YOROI-App to see your wallets
Click on one of your wallets
Click on „Receive“
Copy the address to your clipboard
On Binance select „Wallet“ ->“Overview“ on the right side.
Click on „Withdraw“
Than choose „Crypto“. In the „Coin“-field you write ADA
On The right side you write the adress of your yoroi wallet and the amount of ADAs you want to send to your yoroi adress.
Press „Submit“
After some minutes your YOROI wallet should receive the ADA. In the worst case it takes about an hour
